Abstract
The results of experimental study of the excessive hypersound absorption in an aqueous acetone solution are discussed based on the conclusions of the theory of high-frequency sound scattering near the critical point (developed by Chaban) and the Landau theory. These results are described within the framework of the Landau and Chaban theories and explained by the existence of two different states with minimum thermodynamic stability in the solution. The main conclusions of the theory are presented, and a method for measuring the absorption coefficient of hypersound near the temperature of the unstable thermodynamic state is described.
